Hi there,
I normally use KDE4 as a fallback WM, so I don't know when exactly this problem started to occur: I start KDE with a startx from the terminal (I don't use a login manager) and when I get to KDE there is no windows decoration. Worse than that, every windows is placed on the left top corner, and they cannot be manipulated (moved, resized, minimized, raised or lowered, etc). Curiously enough, windows not relying on kwin (audacious, chrome, etc) can be used normally.

The missing symbol comes from kde-base/libkworkspace. It does not appear in the update list. Could you look which version you have installed? And when?
I am sure that installing libkworkspace-4.9.5 + doing an emerge -uDNavt world will fix you issue._________________"der mac dennoch wesen geil"

Given the number of updates on that list, are you mixing different versions of kde packages (that is you have i.e. some from KDE 4.8 and some from KDE 4.9) ?

Not that I am aware of.

Unless in the meantime you've run all of those updates, you've just contradicted yourself.

Not if I wasn't aware when I wrote, which is exactly the case. But luckily, we're not playing a "battle of words" game, are we?

ok, do this:

Nothing. Still the same error.

However, I did realise that no kde package is in my world, so "emerge world" does not update it. The bug probably comes from the fact that one or two packages in my world pulled in libkworkspace (which was in version 4.9.5) and kdebase-data (which was 4.9.3) but not the others (which were in 4.8.4). I'm updating as I type this, and adding kdebase-meta to world to avoid future problems...
